The Muslims' spirits rose very high. Before this battle, it was inculcated in the hearts of a lot of people that the Tatars could hardly be defeated; and now, the union of the Islamic armies in Ghaznah produced its fruits. In this battle, a union was established between the armies of Jalaal Ad-Deen, the remains of his father's army, the Turkish brigade led by Sayf Ad-Deen Bughraaq, and Maalik Khaan, the governor of Herat. The Muslims then chose a suitable place (for the battle), and utilized all available means. Thus, victory was their share.

Jalaal Ad-Deen then did rest assured about his army, and sent to Genghis Khan in Taloqan, inviting him to another round. Genghis Khan was worried for the first time. He dispatched a greater army under the leadership of one of his sons to fight the Muslims. The Muslim army, in turn, prepared; and both armies met in Kabul, the Afghani fortified city, surrounded from almost all its sides with mountains: the high mountains of Hindu Kush in the North, Paropa Mizus in the West, and the Mountains of Solomon in the South and East.

There, the great battle of Kabul broke up, and the fighting was more ferocious and brutal than in the previous battle of Ghaznah. The Muslims were steadfast and achieved a great victory over the Tatars, and succeeded to rescue tens of thousands of the Muslim captives from the hands of the Tatars. The Muslims did not only have their spirits raised high, killed a great number of the Tatars, and rescued thousands of Muslim war prisoners from the hands of the Tatars, but they also took a great deal of precious and valuable war spoils from the Tatarian army. However, instead of becoming a great favor upon the Muslims, those spoils turned to be a curse and a cause of certain destruction.

In this connection, it was narrated on the authority of ‘Amr ibn ‘Awf, May Allaah Be Pleased with him, that he said that the Messenger of Allaah, sallallaahu ‘alayhi wa salam, said: "By Allaah, I do not fear for you from poverty in so much as I fear for you that worldly wealth will be bestowed upon you as it was bestowed upon those who lived before you, whereupon you will compete with each other over it, as they competed with each other over it, and it will destroy you as it destroyed them." [Al-Bukhaari and Muslim]

At that point of time, the hearts of the Muslims suffered from the chronic disease of attachment to this world, save those upon whom Allaah The Almighty Bestowed His mercy. Their wars were for material and national purposes, intended to serve worldly benefits and inclinations, rather than being in the Cause of Allaah. Their victory for the first and the second time was sought out of love for survival and desire for sovereignty, and for fear of falling captives or being killed. This is why they gained one or two rounds only, after which their hidden intentions appeared when the wealth and booty they gained became much.

The Muslims fell into trial. They disputed over the distribution of the booty. Sayf Ad-Deen Bughraaq, the Turkish king, and Maalik Khaan, the governor of Herat, demanded their shares of the war spoils. There was a dispute and word clashes which led to sword clashes. Yes, sword clashes between the Muslims over the distribution of the booty; at the time the Tatarian armies were still occupying most Muslim cities. There were Muslim victims who fell at the hands of Muslims. One of those was a brother of Sayf Ad-Deen Bughraaq, who grew angry and decided to withdraw from the army of Jalaal Ad-Deen, along with his 30,000 fighters. In this way, the Muslim army was put to great trouble.

Jalaal Ad-Deen tried to solve the problem, and hastened to meet Sayf Ad-Deen Bughraaq, beseeching him to return to the row of Muslims, since the Muslims were in need of all soldiers and power, not to mention the negative effect of that withdrawal on the spirits of the remaining Muslims, as the Turkish brigade was one of the most skilled among the Muslim fighters. However, Sayf Ad-Deen insisted on the withdrawal. Jalaal Ad-Deen stimulated his sympathy in every possible way, and went to meet him by himself, reminded him of (the duty of) Jihaad, and frightened him of Allaah the Almighty. But Sayf Ad-Deen Bughraaq did not remember, and actually withdrew with his army.

In this way, the army of the Muslims was tremendously broken; they were spiritually and materially beaten. The Muslims failed to invest the valuable victory they achieved in both Ghaznah and Kabul.
It was narrated on the authority of Abu Sa‘eed Al-Khudri, May Allaah Be Pleased with him, that the Messenger of Allaah, sallallaahu ‘alayhi wa salam, said: “The world is sweet and green (alluring) and verily Allaah Is going to Make you as vicegerents in it in order to see how you act. So safeguard yourselves from (the temptation of) this world and avoid (the allurement of) women." [Muslim]

However, (unfortunately) at that point of time, the Muslims failed to fathom the real nature of this world as being but an abode of vicegerency, trial and testing, rather than a house of abidance, survival and eternity. They indeed forgot the trial of their Lord the Almighty, and did not prepare for it. They forgot the serious Prophetic warning: "safeguard yourselves from (the temptation of) this world", thereupon they collapsed in a horrifying manner.

Such being the case; Genghis Khan came by himself leading his armies to see that Muslim person who succeeded to emerge victorious twice over his soldiers. Terror and horror crept into the army of the Muslims, since they became less in number and their spirits were down. Jalaal Ad-Deen saw to what extent his army weakened. Then, what did he do? He took his army and moved Southward in flight from, or at least in avoidance of fighting with, the army of Genghis Khan under such circumstances.

But Genghis Khan insisted on meeting him. So, he ran after Jalaal Ad-Deen, who started to do the same as his father had previously done, i.e. to move from a city to another Southward until he arrived at the borders of Pakistan, which he broke in and went deeper until he exceeded the entire territories of Pakistan and reached the Indus River, which was separating, at that time, between India and Pakistan.
Jalaal Ad-Deen intended to cross with his army the Indus River to India, and although his relations with the Muslim governors of India were not good, this was, for him, better than facing the armies of Genghis Khan.
